Acu-rite II DRO help

I installed an Acu-rite2 DRO on my lathe. It is off from a mill as
it has the X & Y axis on the readout. Anyway, I disassembled the
scales, cut the glass and modified the aluminum housings to fit my
9x20 lathe (which went much better than I had anticipated). It is as
accurite as ever with the exception that it reads exactly. 1k on the
readout is 2k off the diameter (it reads radius). The DIP switches
inside have allowed me to get close (i.e. 10k actual=18k on the
readout), but it would take forever to go through every combination
when there are 9 individual switches on the dip! 9 to the 9th
power! If I have to use it like it is that is just peachy. I am
very happy with it. But after being spoiled with a Newall DRO on my
lathe at work, it would be nice to have it read "normally". Any
suggestions? Thanks.
